I think it is clearly obvious that the evapotranspiration and general water balance sheet is not an edge calculation. A cloud server is involved in deciding future waterings (at least with the daily flex that I use). I’ve been told that the calculation behind it is pretty intensive and cannot be handled locally. In other words, your Rachio, even with local Tempest integrations, cannot perform any Flex schedule completely offline. I would like it to be self sufficient.
